Federal Register Proposed Rules, Rules and Notices for May 31,2013

May 31,2013


Notice of Intent To Rule on Request to Release Airport Property at the Fort Worth Spinks
Airport, Fort Worth, Texas [FR DOC# 2013-12872] SUMMARY: The FAA proposes to rule and invite public comment on the release of land at the Fort Worth Spinks Airport under the provisions of Section 125 of the Wendell H. Ford Aviation Investment Reform Act for the 21st Century (AIR 21).


Proposed Airworthiness Design Standards; AQUILA Aviation by Excellence GmbH, Model AT01 [FR DOC# 2013-12176] SUMMARY: This notice announces the issuance of the design criteria for Night visual flight rules (VFR) expansion and substantiation for the Aquila GmbH AT01. These additional provisions are expansions of the existing JAR-VLA (Joint Aviation Requirements–Very Light Aircraft) and CS-VLA regulations to include Night VFR. The current regulations only allow Day VFR, but the European Aviation Safety Agency (EASA) is expanding the VLA regulations for this type of airplane through EASA special conditions. These FAA design criteria are being proposed to be the same as the EASA Special Conditions.

Airworthiness Directives; Bombardier, Inc. Airplanes [FR DOC# 2013-12897] SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-2D24 (Regional Jet Series 900) airplanes, and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This proposedAD was prompted by reports of erratic pitch movement and oscillatory behaviors of the elevator control system. This proposed AD would require repetitive replacement of the bellcrank supports on the inner rear spar of the horizontal stabilizer with new, improved bellcrank supports. We are proposing this AD to prevent erratic pitch movement and transient accelerations, which could result in a significant pitch upset, and injuries to
passengers and flightcrew.



Airworthiness Directives; Turbomeca S.A. Turboshaft Engines [FR DOC# 2013-12696] SUMMARY: We are superseding an existing airworthiness directive (AD) for Turbomeca S.A. Arrius 2B, 2B1, and 2F turboshaft engines. That AD currently requires replacement of injector manifolds and borescope- inspection of the flame tube and the high-pressure (HP) turbine area for possible damage. This new AD requires, depending on the engine model, repetitive replacements of fuel injection manifolds and the privilege injector, or, repetitive
replacements of the privilege injector. This AD was prompted by a report that the
corrective actions of the existing AD were insufficient to eliminate the unsafe
condition. We are issuing this AD to prevent an uncommanded in-flight shutdown of Arrius
2B1 and 2F turboshaft engines and damage to the helicopter.

Establishment of Class E Airspace; Boothbay, ME [FR DOC# 2013-12769] SUMMARY: This action establishes Class E Airspace at Boothbay, ME, to accommodate a new Area Navigation (RNAV) Global Positioning System (GPS) special Standard Instrument Approach Procedure (SIAP) serving St. Andrews Hospital Heliport. This action enhances the safety and airspace management of Instrument Flight Rules (IFR) operations within the National Airspace System. Also, geographic coordinates are corrected under their proper heading.
